For that reason, the exact ingestion cannot be confirmed with out updating the tactic with new obtainable unique markers. The introduction of AMB‐FUBINACA which gives the exact same metabolite as AB‐FUBINACA is definitely an example of the latter.19 Proposed chemical structure with the correct-mass fragments observed for a AMB-FUBINACA and https://prosyntheticchems.com/product/ab-fubinaca/
